About the team:

The Apple Developer Experience team sits within the Foundation Group. At Goodnotes, our Foundation teams ensure that the app experience is seamless, responsive, and resilient, no matter how complex the product becomes. As a Senior iOS Engineer in the Apple DevEx team, you will help your fellow iOS Engineers be more efficient. You’ll collaborate with other teams to ensure you understand their pain points and nuances. You will advise and drive architectural improvements that help our app scale with our growth. Join us in helping Goodnotes ship more, better and higher quality code to maximise the impact on our users.

You’ll be:

• Build mission‑critical services used by tens of millions of users.
• Architect and design scalable solutions that are easy to maintain to allow the development of exciting features and support more users.
• Implement elegant solutions with clean code.
• Help solving the most critical developer problems with a large, offline first, old codebase: Modularization, build times, and a fast and reliable CI/CD
• Define and drive the completion of new initiatives and features by removing blockers for the team
• Continuously improve the development practices through research, automation, documentation and testing
• Share your knowledge and experience with the rest of the team

You’ll need:

• Expertise in Swift programming.
• A strong understanding of computer science fundamentals and an enjoyment of solving algo and data structure puzzles.
• Excellent problem solving, communication, and storytelling skills
• A love of software craftsmanship
• Strong sense of the best tools for any task
• High sense of autonomy
• Knowledge of the best AI tools that can assist with the task at hand
• Proven experience working on sizable and complex codebases
• Big plus if you have experience cross‑compiling codebase on different mobile platforms

Even if you don’t meet all the criteria listed above, we would still love to hear from you! Goodnotes places a lot of value on learning and development and will support your growth if needed.

The stack:

• Programming Language: The vast majority of our code is written in Swift
• CI / CD: We use CircleCI although we’re slowly migrating to TeamCity.
• Concurrency: We have a large, old, but modular codebase. We use modern Swift Concurrency as much as possible as we gradually move away from RxSwift
• UI code: As much new UI code as possible is in SwiftUI. We fall back to UIKit when needed and re‑use the majority of it on macOS using Catalyst
• Cross‑platform: We re‑use our core packages on cross‑platform using SwiftWasm, UI for other platforms is written using React or their respective native APIs
• Dependencies: We exclusively use Swift Package Manager and frequently make new local packages
• Source control and builds: We have a mono‑repo and use GitHub and Pull Requests. We kick off builds using a Slack bot
• Continuous Integration: We use CircleCI which means our configuration is checked in with our code. We have unit tests for all of our modules which run on every branch. UI tests are run daily and before release
• Release cadence: We QA and release on a weekly schedule

The interview process:

• Introduction: The Talent Team want to hear more about your background, what you are looking for, and why you’d like to join Goodnotes.
• Technical Screening: A timed coding challenge on the Hackerrank platform.
• Onsite Live coding & Technical interview: A live coding call with one of our engineers. This is where you get to see what it would be like working at Goodnotes as well as the chance to ask any engineering questions you may have
• AI literacy interview: A short conversation with an AI Champion on your understanding and use of AI tools
• Hiring Manager interview: A call with your hiring manager. This is the person who will be managing you day to day, working on your growth and development with you as well as support you throughout your career at Goodnotes.
• Values interview – Meeting with members of the Goodnotes Team to answer questions relating to take ownership AND build great things
